　　Ⅲ. 单句改错

　　1．I didn't know what one to buy because these books were all useful to me.

　　答案与解析：what→which　此处表示“不知道该买哪一个”意义，故“疑问词＋不定式”结构中的疑问词应用which。

　　2．You want to know that everthing is going in our school.

　　答案与解析：that→how　宾语从句的引导词在从句中作状语，表示go的程度，表示“我们学校的情况如何”，故用how。

　　3．The problem is what the “Play” doesn't work at all.

　　答案与解析：what→that　表语从句的引导词在从句中不作成分，而且不表示意义，故用that。what在名词性从句中需要作主语、宾语等。

　　4．There is no doubt whether I will achieve great progress in English learning with your assistance.

　　答案与解析：whether→that　否定句或疑问句中doubt后的从句用that引导，肯定句doubt后的从句用whether/if引导。There is no doubt that...“毫无疑问……”。

　　5．At that time， I just wondered that my mother was so delighted.

　　答案与解析：that→why　根据wonder判断，引导词表示“为什么”意义，故用why。句子表示“我不明白为什么妈妈那么高兴”。

　　6．Which is worse， they spat and even threw rubbish into the lake.

　　答案与解析：Which→What　What is worse是固定用法，意为“更糟糕的是”。

　　7．I went up and asked what I could help them.

　　答案与解析：what→if/whether　 宾语从句的引导词不需要在从句中作成分，再根据ask判断句子的引导词表示疑问意义，故应为if/whether。

　　8．As is known to all that millions of graduates crowded into the job market each year.

　　答案与解析：As→It　本句是一个it作形式主语，that引导的从句作真正主语的句子，故改为it。如果用as，则为As is known to all， millions of graduates...。

　　9．That you should learn is how to write down the most important words， not the whole sentence.

　　答案与解析：That→What　主语从句的引导词需要在从句中作learn的宾语，故用what。

　　10．The main reason for this was because my mother didn't know how to cook anything when she got married.

　　答案与解析：because→that　was后是表语从句且从句中不缺少成分，故用that引导。
